The cardiovascular system responds dynamically to exercise by increasing heart rate, enhancing blood flow, and improving oxygen delivery to muscles. During physical activity, the body requires more oxygen, prompting the heart to pump faster and more efficiently. Vasodilation occurs in active muscles, allowing greater blood flow while blood vessels constrict in non-active areas. Additionally, regular exercise leads to long-term adaptations, such as increased stroke volume and improved cardiac output. This systemic response not only supports better physical performance but also contributes positively to overall cardiovascular health.
